Aero-Optimised Speed. Lightweight Race Precision.
The 2026 Giant Propel Advanced SL 1 is a high-performance aero road bike engineered for riders who crave speed, precision, and aerodynamic advantage. It delivers race-level efficiency in a refined, lightweight carbon chassis, making it a standout choice for fast group rides, criteriums, and solo efforts where every second counts.
Race-Winning Carbon Engineering
The Advanced SL-grade composite frame and fork are crafted using Giant’s advanced materials and methods. The result is a frame that’s exceptionally light, gaining approximately 150 grams in weight savings, while maintaining maximum stiffness-to-weight performance.
Integrated Aero Efficiency
Featuring AeroSystem Shaping, every tube and angle is optimized using CFD to deliver minimal drag across yaw angles. The integrated seatpost adds aerodynamic smoothness and compliance, while streamlined cable routing through the stem and head tube ensures a clean and service-focused cockpit.
Premium Aero-Specific Components
Equipped with Shimano Ultegra Di2 electronic shifting and hydraulic disc brakes, the Propel Advanced SL 1 offers precise control and clean performance. It rolls on Giant’s Elite-level carbon SLR 1 50 Aero wheelset and is fitted with CADEX Aero tubeless tyres for speed and low rolling resistance.
